[PATCH] Don't clean temporary files in child processes

[Niko Tyni]

As of SQLite 3.7.0, write locks try to stat() the database
file and fail with a 'Disk I/O error' if it is missing. This
breaks those tests that fork child processes (namely 08_busy.t
and t/28_schemachange.t) because the child process removes
the database file in the END block.

The fix is to disable the clean() function for child processes.
